Page 120 - Scotia contained no regular reservation of minerals. In some instances gold, silver, and precious stones only were reserved ; in other cases gold, silver, iron, copper, lead, &c., were retained for a source of revenue to the Crown.
Page 108 - River series, of which it forms a part, but it contains little or no admixture of foreign materials, and is uniform to texture and in unequalled abundance. The following varieties have been recognized : — 1. Fine white statuary marble. 2. Fine white building " 3. Coarse white building " 4. Blue and white clouded marble. 5. Brocatello marble, mixed with six varieties of colored marbles. 6. Fine flesh-colored marbles, often striped and variegated. The locality offers every facility for quarrying...
Page 108 - Breton, several places are known which afford marble believed to be well adapted for building and decorative purposes. The finest deposit of workable limestone yet discovered is on West Bay, Bras d'Or Lake. In variety of color and tint this rock resembles the limestones of the George River series, of which it forms a part, but it contains little or no admixture of foreign materials, and is uniform to texture and in unequalled abundance.
Page 46 - The depth to which mining can be successfully carried is, under any circumstances, so iiifinitesiinally small when compared with the distances through which the forces supposed to be the cause of the vein-fissures must have opeiated, that there need be no apprehension of the limit of the latter, in depth, being reached at distances less than those through which we know them, (from surface evidence) to extend horizontally in directions parallel and transverse to the anticlinal axes ; and as these...
Page 111 - ... apparently contain a fair percentage of graphite. The occurrence of graphite has also been reported from West bay, Grand Narrows, East bay and Hunters island, and in addition, Mr. Gilpin, in his Report of the Mines of Nova Scotia, 1880, mentions its presence, mostly in the form of plumbaginous shales, at Parrsborough, Salmon river, Musquodoboit, Hammonds plains, Fifteen-mile stream Boularderie island, Gregwa brook, and Gillis brook, the last three being in Cape Breton.
Page 12 - Judging from appearance, this coal, which is of the bituminous kind, seems to be of excellent quality.
Page 78 - ... of disturbance is marked by metamorphism, and by the presence of associated ores of iron and copper. The principal localities where the latter occur are noticed by the author, who states that the copper deposits attain their greatest development near Lochaber Lake and Poison's Lake, where they form a series of veins, cutting at oblique angles black and red shales and quartzites, apparently of somewhat doubtful age. The quality of the ore is said to be good. 13. "Glacial Drift in the North-eastern...
Page 57 - ... action. Mr. Mushet writing to Mr. C. Archibald, said : — " The shell ore is quite a novelty, and the magnetic character of some of the pieces contrasts strongly with the inert state of others to all appearance of similar composition. I have examined it and find that it is curiously comprised of magnetic and non-magnetic lamin;*'. The assay of the former gives 67 1 per cent, and the latter 54 per cent*.
Page 57 - One Jackson. cannot fail to be surprised at the enormous quantities of ore which are already exposed by the numerous openings that have been made. There are several distinct and parallel beds of iron ores which we examined, from four to ten feet in width, extending certainly no less than five miles continuously. * * * The supply of iron ores at Nictaux is inexhaustible.
Page 65 - The ore is compact, concretionary, and fibrous, with considerable quantities of gravel ore. At two points the ore has been proved to rest on the Silurian clay slates, and has Limestone on the hanging wall, usually with a gore of red clay, frequently holding concretions of Manganite and Pyrolusite intervening. These ores are very pure, and appear to be much more free from phosphorus than the Londonderry limonite, the average of five analyses of the East River ore giving -118 phosphoric acid, or -083...
